### Question: What causes Trichomoniasis?
### Response: Trichomoniasis is found worldwide. In the United States, the highest number of cases are seen in women between age 16 and 35. Trichomonas vaginalis is spread through sexual contact with an infected partner. This includes penis-to-vagina intercourse or vulva-to-vulva contact. The parasite cannot survive in the mouth or rectum.
The disease can affect both men and women, but the symptoms differ between the two groups. The infection usually does not cause symptoms in men and goes away on its own in a few weeks.
